Ultra-water process for the preparation of chemical industry roughly divided into the following categories: - EDI ultra-pure water equipment 1, the use of ion exchange, the process is as follows: Raw water → raw water pressure pump → → Multi-media filter activated carbon filter softener → → precision filter → cation resin filter bed → anion resin filter bed → yin and yang resin mixed bed → → water points micropore filter 2-stage reverse osmosis methods, the process is as follows: Raw water → raw water pressure pump → Multi-media filter → activated carbon filter softener → → → precision filter regulator first stage reverse osmosis → PH → intermediate tank → second stage reverse osmosis (RO membrane surface with positive charge) → purification tank → pure water pump → microporous filter → 3 water points, using EDI, the process is as follows: Raw water → raw water pressure pump → → Multi-media filter activated carbon filter → → → precision filter water softener reverse osmosis machine → intermediate tank → middle of the pump → EDI system → microporous filter water → water points, the concept of ultra-pure water and compare: - EDI ultra-pure water equipment 1, also known as pure water EDI ultra-pure water equipment supply Hainan, refers to meet the drinking water health standards of water as raw water Hainan EDI ultra-pure water equipment, by electrodialysis, ion exchangers, reverse osmosis, distillation and other appropriate processing methods, the resulting sealed in a container, and contains no additives, colorless, transparent, drinkable water. Space water on the market, distilled belong to pure water. 2, ultra-pure water is further conductive medium almost completely removed on the basis of pure water, colloidal substances turn undissociated water, gas and organic matter are removed to the low level of water. Resistivity greater than 18MΩ * cm, or nearly 18.25MΩ * cm limit. Ultra-pure water is difficult to achieve the degree of the general process can be microfiltration technology, ultrafiltration, reverse osmosis technology, EDI technology, ion exchange technology in two or more of the technology, through a reasonable process design EDI ultrapure Hainan wholesale water equipment, equipment selection, only manufacturing trade surplus Hainan EDI ultra-pure water equipment procurement, resistivity up 18.20MΩ * cm. The difference between pure water and ultrapure water: - EDI ultra-pure water apparatus 1, the conductivity is different between the water conductivity 2-10us / cm, the conductivity of ultrapure water 0.056us / cm; 2, manufactured different degree of difficulty, water use on the market today are basically through reverse osmosis, distillation or the like in the system, while the ultra-pure water is also through photo-oxidation technology, fine processing and polishing process on the basis of pure water, etc. a complex series of purification techniques prepared; 3, heavy metals, bacteria, and other indicators of the number of particles is also very different, water impurities are ppm level, while the ultra-pure water for the ppb level, simply ultrapure water has no What impurities, close to the theoretical water; 4, is not the same as used in the art.
